Now, Lin Yun in Shen City could obtain thirteen spirit crystals every day from the Cosmic Trading System.
If the energy absorbing range of the Cosmic Trading System expands by four times, Lin Yun in Shen City could obtain more than fifty spirit crystals each day.
He wouldn't need twenty days to acquire a thousand spirit crystals.
Not to mention, for every hundred spirit crystals he obtains, he could first expand the energy absorbing range of the Cosmic Trading System by a hundred meters.
If it was so, he could have acquired many more spirit crystals before he got a thousand of them.
If he kept storing up the spirit crystals without spending them, until he reached a thousand, this would result in a waste of those crystals.
